I practiced a similar question, and I believe the Transform phase is key for R programming, especially for cleaning and reshaping data.

I'm not entirely sure, but I remember something about R being used for data extraction too. Maybe it's the Extract phase?

I think the R skills would be most relevant during the Transform phase since that's where data manipulation happens, right?
